Additional cleanups in QuerydslAwareRootResourceInformationHandlerMethodArgumentResolver to make sure a QuerydslRepositoryInvokerAdapter is only applied if the QuerydslPredicateBuilder actually exposes a predicate. Extracted a couple of methods to make sure the mapping pipeline reads nicely.
We now interpret If-None-Match and If-Modified-Since headers on requests to resources backed by query methods returning a single instance only. This allows clients to optimize GET requests to those resources to save bandwidth.
Previously, NestedEntitySerializer failed to handle Maps correctly as the logic to convert the found values to nested resources tried to handle the values as is, not explicitly looking at the values instead.
We now use an explicit code path to turn the values into resources so that links pointing to other resources are rendered correctly.
Original pull request: #219.
Upgraded to JSONPath 1.1.0 as 0.9 is not supported with Spring 4.2 anymore. Tweaked integration tests due to changed semantics and internals of JSONPath >= 1.0.
Extracted store specific tests into separate test modules to prevent classpath overlap between projects. Those tests are now executed in an "it" build profile to prevent the tests being packaged for distribution on release.
Use Map-based repositories and mapping contexts for test in the Core and WebMvc module.
Slightly changed the configuration API for lookup types on RepositoryRestConfiguration.
